Comment 6 for bug 1933880

A workaround of my own was to correct the nvidia driver's behaviour.

Running Ubuntu 21.04 and nvidia-drivers-460, I upgraded to nvidia-drivers-470 (which I had installed once before), resulting in no masked services, and files paths to real .service files.

Before:
❯ systemctl status nvidia-suspend nvidia-hibernate nvidia-resume
● nvidia-suspend.service
     Loaded: masked (Reason: Unit nvidia-suspend.service is masked.)
     Active: inactive (dead)

● nvidia-hibernate.service
     Loaded: masked (Reason: Unit nvidia-hibernate.service is masked.)
     Active: inactive (dead)

● nvidia-resume.service
     Loaded: masked (Reason: Unit nvidia-resume.service is masked.)
     Active: inactive (dead)

After:
systemctl status nvidia-suspend nvidia-hibernate nvidia-resume
● nvidia-suspend.service - NVIDIA system suspend actions
     Loaded: loaded (/lib/systemd/system/nvidia-suspend.service; enabled; vendor preset: enabled)
     Active: inactive (dead)

● nvidia-hibernate.service - NVIDIA system hibernate actions
     Loaded: loaded (/lib/systemd/system/nvidia-hibernate.service; enabled; vendor preset: enabled)
     Active: inactive (dead)

● nvidia-resume.service - NVIDIA system resume actions
     Loaded: loaded (/lib/systemd/system/nvidia-resume.service; enabled; vendor preset: enabled)
     Active: inactive (dead)
